-l Claim.

construction, combination and arrangement of parts through the medium ofwhich all objectionable odors will be drawn from the bowl.

Another very important object of the invention is to provide aventilated toilet of thetype including an exhaust fan driven by anelectric motor, together with novel means for controlling the current to`said motor.

Still further objects and advantages of the invention will becomeapparent from a study of the following specification, taken inconnection with the accompanying drawings wherein like characters ofreference designate corresponding parts throughout the several views,and wherein:-

Figure 1 is a top plan Lview of a ventilated toilet constructed inaccordance withthe present invention. 1

Figure 2 is a view in vertical longitudinal section through theinvention'.

Figure 3 is a fragmentary view in verticaltransverse section, takensubstantially on the line 3-3 of Figure l.

Figure 4 is a fragmentary view in vertical longitudinal section, takensubstantially on the line 4-4 of Figure 3. v

Figure 5 is a fragmentary view in horizontal section, takensubstantially on the line 5--5 of Figure 4.

Figure. 6 is a fragmentary view in side elevation, showing the mountingof the seat and co'ver.

Figure '7 is a horizontal sectional view, taken substantially ony theline'7-7 of Figure 2.

Figure 8 is a diagrammatic View of the electric circuit.

Referring now to the drawings in detail, it will be seen that theembodiment of the invention which has been illustrated comprises a bowl1 having itsl upper portion formed to provide a water channel 2 abovewhich is formed a suction channel 3. The water channel 2 is providedwith outlet openings 4 in itsA lower portion and the suction channel 3is provided with inlet openings 5 inv its inner periphery. Of course,the channel 2 receives water from the usual flushing apparatus, as willbe understood.

Rising from the rear portion'of the bowl 1 is a pair of angularstandards 6 to which a seat 7, of any suitable material, is hingedlyconnected by hangers 8. Also iournaled between the standards 6 is acover` 9 for the seat 7. The seat 7 in- 1934, Serial No. 306,873

cludes a body 10 which is split at its rear for the reception ofavhollow insert 11. The insert 11 is preferably of metal and is securedin position by perforated wings 12 which are embedded in the adjacentend portions of the body 10. A sealing bead 12' depends from the body l0of the seat 7 for engagement with the top of the bowl 1 when the toiletis in use. It will thus be seen that the body 10 of the seat, when inlowered position, will be spaced from the bowl 1.

Extending rearwardly from the upper portion of the bowl 1 is a suctionconduit 13 having communication with the suction chamber 3 and the spacebetween the body 10 of the seat and the bowl 1, as illustrated toadvantage in Figure 2 ofthe drawings. Mounted on the forward portion ofthe suction conduit 13 is a substantially U- r shaped gasket 14 withwhich the rear end of the insert 11 is engageable for providing aleak-proof joint between the seat 7 and said conduit 13 when said seat 7is in lowered positioxn Projecting rearwardly lfrom the standards 6 Kare angular arms-15 upon which the springs 16 are mounted, said springsbeing operatively engaged with the seat 7 for yieldingly supportinglsaid seat in slightly elevated position when the vtoiletvis not in use,as indicated in broken lines in Figure 2 of the drawings. A'I'he arms 15are provided with reduced free end portions (see Figures 3 and 5) whichproject through the gasket 14 and upon which insulated contacts 17 aremounted. From the foregoing it may be seen that the arms 15 mayconstitute means for vsupporting the resilient gasket 14' in position.The contacts 17 are engageable by the end portions of an insulatedbridge member lwhich is mounted in the insert 11 of the seat 7. It willthus be seen that a switch; which is designated generally by thereference numeral 19, is provided for automatically controlling theexhaust fan motor, said motor being designated by the reference numeral20 in Figure 8 of the drawings. Of course, one of the contacts 17 iselectrically connected with the motor 20 while the other of saidcontacts is con- Y nected with a source of current supply.

Briey, the operation of the invention is as followsz- When the toilet isnot in use the seat 7, asv hereinbefore stated, is yieldingly supportedin slightly raised or elevated position by the springs .16. With theseat in this .position the motor 20 is deenergized, the switch 19 beingopen as the bridge member 18 is disengaged from the contacts 17. Whenthe toilet is in use, the weight of the occupant depresses the seat '7against the tension of the springs 16 thereby closing the switch 19 forenergizing the electric motor 20 and, of course, the exhaust fan, (notshown) is actuated. A suction is thus created in the chamber 3 andaround the top of the bowl l for drawing odors from said bowl, as willbe readily understood. When the seat 7 is released the springs 16 willagain raise said seat to the broken line position shown in Figure 2 ofthe drawings thereby opening the switch 19 for deenergizing the electricmotor 20.

It is believed that the many advantages of a ventilated toiletconstructed in accordance with the present invention will be readilyunderstood, and although the preferred embodiment of the invention is'`as illustrated and described, it is to be understood that changes in thedetails of construction and in the combination and arrangement of partsmay be resorted to which will fall lthe interior of the bowl, a suctionconduit connected to said bowl, a hinged connection between the seat andthe conduit, means for raising the seat proper a slight distance abovethe' bowl, the bowl end of the suction conduit being partly incommunication with the said passageway and partly in communication withthe space between the bowl and the seat.
